How do i made a vertex group for all objects
your question for &quot;how do I attach a vertex group to a bone&quot; is answered by how-to-assign-vertex-group-to-single-bone, although you can assign to more than one group in succession, I believe (and then perhaps need to adjust weights if &gt;1 group).  Here I took a sphere and parented it (Armature Envelope weights), which generally would parent it mostly to the right arm and spine area.   I then put the sphere in edit mode, selected some vertices , created and assigned to a new &quot;group1&quot; (just I could select them later if needed), but ALSO assigned them to the automatically created group &quot;hand.L&quot; (left hand).  As you can see when I posed the Armature to swing the Left arm upwards, my selected vertices of the sphere tracked with the left hand position.   Here's my blend example:
